Early Read Wait State
In some cases, the SMC inserts a wait state cycle between a write access and a read access to
allow time for the write cycle to end before the subsequent read cycle begins. This wait state is
not generated in addition to a chip select wait state. The early read cycle thus only occurs
between a write and read access to the same memory device (same chip select).
• An early read wait state is automatically inserted if at least one of the following conditions is
• if the write controlling signal has no hold time and the read controlling signal has no setup time
• in NCS write controlled mode (WRITE_MODE = 0), if there is no hold timing on the NCS signal
• in NWE controlled mode (WRITE_MODE = 1) and if there is no hold timing (NWE_HOLD = 0),

valid:
(Figure
and the NCS_RD_SETUP parameter is set to 0, regardless of the read mode
The write operation must end with a NCS rising edge. Without an Early Read Wait State, the
write operation could not complete properly.
the feedback of the write control signal is used to control address, data, chip select and byte
select lines. If the external write control signal is not inactivated as expected due to load
capacitances, an Early Read Wait State is inserted and address, data and control signals are
maintained one more cycle. See
